Abstract
A coiled RFID tag that includes an RFID transponder circuit that is formed over a generally cylindrically-shaped substrate core so that portions of the antenna of the transponder circuit circumscribe the substrate core. With this configuration, the tag may be applied to objects without regard to antenna orientation. The transponder circuit and substrate core are encased in a protective material that will prevent ingress of moisture and dust, insulate from heat and cold but will allow radio frequency waves to pass without significant attenuation. The tag may be attached various items by an overmolding process in the formation of a grip of other portions. Alternatively, the tag may be attached to objects by forming it into a flexible sleeve-like portion that is pulled over objects and maintained in position by the resilient properties of the sleeve.
